Guys who like to make thier own PCB's should check this out: A couple of guys figured out how to modify thier old Epson inkjet printers and found the right inks and process to directly feed PCB stock and print the echant resist at high resolution directly!

Once you can feed the PCB through the printer for etch resist, you can then feed it back through the printer for solder mask (yep, it masks solder!) and for component placement "silk-screen."

Considering how little you can get an old Epson C84 on eBay and the low cost of the inks (from a refiller outfit) this has got to be the cheapest way to prototype PCBs.

Anyone else have any favorite methods?
